Each year, Nike's Ease Challenge tasks footwear designers to think up new shoe concepts that make it easier for disabled athletes to exercise and compete. This year, the winning shoe features a modification that Brett Drake, its inventor, refers to as a "drawbridge." The shoe, which takes the Nike Hyperdunk as its base, features a hinged, detachable heel that makes it significantly easier for people with limited foot mobility or dexterity to don the shoes.
The drawbridge heel on the Ease Challenge-winning shoe has a hinge toward the sole, and it connects to the back of the heel with light but strong magnets. Once attached, the shoe looks essentially identical to the original Nike Hyperdunk, and that's part of the reason for Drake's winning design's appeal.
